Referring to the drawings in detail, a casing l f.

including ya rear wall 2 and a front wall 3 supports and houses the `clock mechanism for rotating the hour and minute hands 4 and .5, respectively. This mechanism--is the conventional electric `clock mechanism and forms no part of the to armature members 8 connected thereto which e impulses yare transmitted by said armature members to a laminated disc. member 9 positioned between them whereby said disc member is rotated. Disc member 9 is fastened to a shaft i0 carrying a worm II which meshes with a gear I2 ron a shaft I3 disposed at right angles to shaft l0. Shaft I3 carries a worm I4 which meshes with a gear I5 on a shaft I6 disposed at rig-ht angles to shaft I3. Shaft l5 carries a worm I'I meshing with a gear I8 fastened to a shaft or arbor I9 for kdriving the hour and minute hands. The hour hand 4 is fastened to a bushing or sleeve 20 loosely mounted on the arbor `I9 adjacent its outer end, .and the minute hand 5 is secured to a bushing 2| fastened to the outer end of the arbor.

Supported forwardly of the casing by means of posts 22 is a disc member 23 and suitably supported on the sleeve 20 is the clock face or dial 24, disposed on the same plane as the disc. Interposed between the inner periphery of the disc 23 and the clock face is a ring member 25. This ring member 25 rotatesy on a ball bearing device 26 interposed between the disc member and ring member. The ring member 25 is divided into twenty-four sections 25 representing the twentyfour hours of the day and this ring member moves only one-twenty-fourth as fast as the minute hand 5 of the clock.

The sections of the ring member are marked to indicate the hours of the day. The hour of midday or noon is marked with the representation of the sun as indicated at 25x and the hour of midnight may be marked with the representationof the moon (not shown). Reading anticlockwise from noon as viewed in Fig. 1, the sections 25 representing the hours of one oclock P. M. to four oclock P. M. inclusive are marked with the numerals 1, 11, III and 1111, and the sections representing the hours from five oclock P. M. to eleven oclock P. M. inclusive are marked by the Roman numerals V to XI inclusive, midnight being represented by the representation of the moon (not shown). The sections representing the hours from twelve oclock to four oclock A. M. are marked with the numorals 1, IL 111 and 1111. The sections representing the hours from five oclock A. M. to eleven oclock A. M. are marked with the Roman numerals V to XI inclusive, said sections with the exception of the section representing the hour of ten oclock A. M. and P. M. being divided into outer ,and inner sections by a line running -across the center of said sections, with the Roman numerals appearing above and below the lines in reversed positions as seen in Fig. 1. The sections 25 representing the P. M. hours are also divided into outer and inner sections the same as A. M. The P. M. numerals are black on blue background and the A. M. numerals are black on white background for night and day, respectively.

Disc member 23 is divided into twenty-four sections or segments 23 by radial lines 22x in line with the sections 25 and form continuations thereof. The segments bear the names or initials of the.countries, principal cities and islands of the world located` in the same time belt or zones, for example, Batunr Astrakhan and Baku etc. The segments bear only a portion of such names as it is believed that this is suilicient for illustration purposes.

The mechanism for rotating the ring member at the calculated speed will now be described. Supported on the front wall 3 of the casing spaced therefrom by spacers 21 is a plate member 28. Rotatably mounted on the plate 28 is an internal gear member comprising an outer ring member with teeth 29 on its inner periphery and an inner ring member with teeth 39 on its inner periphery. A shaft 3| is journaled in the walls of the casing parallel to the arbor I9 and is divided into a front shaft section 32 rotatably mounted in the front wall 3 and a rear shaft section 33 slidably and rotatably mounted in the rear wall of the casing and in the wall of a bracket 34 secured to the rear wall. The inner end of the shaft section 33 has a keyway coacting with a key 35 on a coupling member 36 fastened on front section 32 whereby the sections 32 and 33 are connected for rotation in unison. Loose on shaft 33 is a gear 31 meshing with gear 38 on shaft I9. Gear 31 has a wedge-shaped socket portion 39 supported by a U-shaped plate or support 49 secured in the casing. Fastened to the shaft section 33 adjacent the gear 31 is a clutch member 4| shaped to conform to the shape of the socket portion and movable into and out of engagement with said socket portion whereby said gear 31 i5 made fast and loose respectively on said shaft section 33. A coil spring 42 urges the clutch member 4| into engagement with the socket portion 39. A pinion or gear 43 is fastened to the front shaft section 32 between the front plate 3 of the casing and the plate 28, and loosely mounted on said shaft section in front of the gear 43 is a gear 44 having an elongated hub portion extending toward the outer end of the shaft section. Fastened to one face of the gear 43 is a large cam member' 45 having three working faces 46, and in front of said cam member 45 is another smaller cam member 41 fastened to the larger cam member, said smaller cam member 41 having three Working The gear 4,4 and the cam' members rotate in unison loosely around the shaft section 32 inside the plate 28.

Pivotally mounted on arbor i9 inside of plate 28 is a bell crank lever, the long arm 49 of which carries a pivot pin which extends outwardly through. a slot 5| in the plate 28. On the outer end of the pin on the outside of the plate 28 are opposed pivoted pawl members 52 and 53, the

nose portion 54 of pawl member' 52 engaging the teeth 29 of the cuter ring member of the internal gear for moving said gear clockwise as viewed in Fig. 5, and the nose portion 55 of pawl member 53 engaging the teeth 30 of the inner ring member for holding the internal gear member against rotation. Nose portion 55 of pawl 53 carries a protruding pin 56. On the outer end of the short arm 51 of the bell crank lever is a roller 53. A spring 59 having one end fixed to the plate 28 and its other end fixed to the long arm 49 of the lever urges the bell crank lever in a clockwise direction as viewed in Fig. 5.

Another lever member 6D is pivotally supported at its center on the outside of the plate 28 by means of a pivot pin 6| mounted on the plate. This lever comprises a wide flat arm 62 extending in the direction of the cam members and a narrower arm 63 extending in the opposite direction toward the pawl members. On the outer free end of arm 62 is a pin 64 extending inwardly through a slot 55 in the plate 28 into the inside thereof and mounted on the pin inside of the plate is a roller 56 engaging the small cam member 41. Arm 63 engages the pin 56 on the nose 55 of the pawl member 53. A spring 61 has one end fixed to the plate 28 and its other end fixed to the arm 62 of the lever 53 for urging said lever in a counter clockwise direction as viewed in Fig. 5.

Referring to Figs. 2 and 4, when the arbor I9 is rotated by the clock mechanism, its drive is carried to shaft 3| by means of the meshing gears 38 and 31. When shaft 3| rotates it carries the cam members 45 and 41 around with it in the direction of the arrow in Fig. 5. Small cam 41 will engage roller 66 on arm 62 of lever member E0 and thereby rock said lever member clockwise on its pivot so that its arm 63 will lift the nose 55 of pawl member 53 up out of engagement with the teeth 30 of the inner ring member of the internal gear member, thus permitting the bell crank lever to be rotated. Cam member 45 following will engage the short arm 51 of the bell crank lever rocking said lever in a counterclockwise direction as viewed in Fig. 5 thereby dragging the nose portion 54 of pawl member 52 downwardly over the teeth 29 in a counterclockwise direction as viewed in Fig. 5. When the working face 49 of the cam member 41 is moved away from the roller 6G on the short arm 51 of the bell crank lever, the spring 59 pulls the bell crank lever in a clockwise direction and the nose portion 54 of the pawl member 52 in engagement with the teeth 39 of the outer ring member rotates the internal gear member and attached ring member 25 clockwise as viewed in Fig. l. When the Working face 48 of the small cam member 41 moves away from the roller 56 on the arm 62 of lever 69, the spring 61 pulls said lever 6I] in a counter-clockwise direction moving the arm 63 away from pin 56 permitting the nose portion 55 of the pawl member 53 to drop into engagement with the teeth 39 of the inner ring member to prevent rotation of the internal gear member until the next working face of the cam member 41 engages the roller B6 again. Plastic posts 26' connect the internal gear to ring member 25 for moving the latter- The drive is brought to the hour hand l4 by means of a gear 68 fastened to bushing 2| and a gear 69 fastened to the arbor I9. Supported by the plate 28 and extending forwardly thereof is a stub shaft 19. Adjacent one end of the shaft are teeth 1| engaging with the teeth of gear 68. The other end of the shaft 19 supports a gear 12 which meshes with gear 69 on the arbor I9.

For adjusting the hands of the clock, shaft 3| is first disconnected from arbor I9 by sliding the shaft section 33 inwardly by means of a knob 13 on its outer end. This will move the clutch member 4| away from the socket portion 39 of the gear 31. The shaft section 33 is held in its inward unclutched position by means of a pin 14 on the sleeve portion 15 of the knob 13 engaging in a bayonet slot 16 formed in the hub portion 11 of the opening in the rear wall of the casing through which the shaft extends. Arbor I9 is then rotated by means of a knob 18 on its outer end turning gear 69 which in turn rotates gear 12land stub shaft 10 carrying teeth 1|. Teeth 1| rotates gear 68 which rotates the bushing 2| supporting the hour hand 4 thereby turning the same for adjustment.

The present invention is concerned with means for illuminating the clock dial and outer disc and ring member 25 of the clock. Supported by a bracket 19 iixed to and extending from plate 28 in the space between the plate 28 and the clock dial are a number of lamps which are in circuit with a source of electric power such as a battery 8| shown diagrammatically in Fig. 3. A plug 82 is shown connected to the casing I for connecting the clock to a source of power and a switch 83 may be conveniently mounted for controlling the lamp circuit. It will be seen that the lamps illu- Inmate the face of the clock, the rotatable ring f member and the fixed disc member so that the the outer periphery of said dial plate in the same plane therewith and operatively connected to the arbor member for rotation thereby and in calculated timed speed therewith, said ring member being divided into a plurality of sections in annular series thereon and arranged concentrically outside of the peripheral range of the local timeindicating dial on the dial plate of the clock, a
